Granulicatella seriolae sp. nov., a Novel Facultative Anaerobe Isolated from Yellowtail Marine Fish
Curr Microbiol. 2023 Nov 24;81(1):13. doi: 10.1007/s00284-023-03523-6.ABSTRACTA bacterial strain, designated as S8T, was isolated from the gut contents of Seriola quinqueradiata from the coastal sea area of Jeju Island, South Korea. The strain is a Gram-staining positive, non-motile, non-spore-forming, facultative anaerobic coccus. Optimal growth was observed at 30 °C, pH 8.0-9.0, and 0-0.5% w/v NaCl, under anaerobic conditions. The predominant fatty acids were C18:1 ω9c, C16:0, C18:0, and C16:1 ω9c, while quinone was not detected. The genome was 2,224,566 bp long, with a GC content of 38.2%. Phylogenetic analysis based...

Situation Report on mcr-Carrying Colistin-Resistant Clones of Enterobacterales: A Global Update Through Human-Animal-Environment Interfaces
Curr Microbiol. 2023 Nov 21;81(1):12. doi: 10.1007/s00284-023-03521-8.ABSTRACTIn the twenty-first century, antibiotic resistance (ABR) is one of the acute medical emergencies around the globe, overwhelming human-animal-environmental interfaces. Hit-or-mis use of antibiotics exacerbates the crisis of ABR, dispersing transferable resistance traits and challenging treatment regimens based on life-saving drugs such as colistin. Colistin is the highest priority critically important antimicrobials for human medicine, but its long use as a growth promoter in animal husbandry reduces clinical efficacy. Since 2015, the emergence an...

Antibiotic-Induced Biofilm Formations in Pseudomonas aeruginosa Strains KPW.1-S1 and HRW.1-S3 are Associated with Increased Production of eDNA and Exoproteins, Increased ROS Generation, and Increased Cell Surface Hydrophobicity
Curr Microbiol. 2023 Nov 17;81(1):11. doi: 10.1007/s00284-023-03495-7.ABSTRACTPseudomonas aeruginosa is a medically important opportunistic pathogen due to its intrinsic ability to form biofilms on different surfaces as one of the defense mechanisms for survival. The fact that it can form biofilms on various medical implants makes it more harmful clinically. Although various antibiotics are used to treat Pseudomonas aeruginosa infections, studies have shown that sub-MIC levels of antibiotics could induce Pseudomonas biofilm formation. The present study thus explored the effect of the aminoglycoside antibiotic gentamicin on...

Fungal Diseases Caused by Serious Contamination of Pharmaceuticals and Medical Devices, and Rapid Fungal Detection Using Nano-Diagnostic Tools: A Critical Review
Curr Microbiol. 2023 Nov 17;81(1):10. doi: 10.1007/s00284-023-03506-7.ABSTRACTFungal-contaminated compounded pharmaceuticals and medical devices pose a public health problem. This review aimed to provide an organized overview of the literature on that critical issue. Firstly, it was found that compounding pharmacies can produce drugs that are contaminated with fungi, leading to outbreaks of severe fungal diseases. Secondly, inadequate sterile compounding techniques or storage conditions, or exceeding the limit of a fungal count, can result in fungal contamination. Lastly, nanotools can be used to rapidly detect fungi, thus...

Predicting Human Risk with Multidrug Resistant Enterobacter hormaechei MS2 having  MCR 9 Gene Isolated from the Feces of Healthy Broiler Through Whole-Genome Sequence-Based Analysis
In this study, a multidrug resistant strain (MDR) of Enterobacter hormaechei MS2 isolated from the feces of healthy broiler chicken has been characterized by whole-genome sequencing-based method. Here, the isolate was primarily subjected to antimicrobial susceptibility testing followed genome sequencing and analysis. From the antimicrobial susceptibility testing result, the strain was found to be resistant to multiple classes of drugs including the colistin which is an important last resort drug used to treat infectious diseases. The resistome prediction of genomic data further revealed the presence of 7 perfect and 26 str...

First Insight into Drug Resistance Genetic Markers, Glucose-6-Phosphate Dehydrogenase and Phylogenetic Patterns of Misdiagnosed Plasmodium vivax Malaria in Far North Region, Cameroon
This study aimed at characterizing drug resistance genes, glucose-6-phosphate dehydrogenase gene (G6PD), and phylogenetic patterns of a Pv + Pf co-infection misdiagnosed as a Pf mono-infection in the Far North region of Cameroon. Only one non-synonymous mutation in the pvdhps gene A383G was found. Pv drug resistance gene sequences were phylogenetically closer to the reference SAL-I strain and isolates from Southeast Asia and Western Pacific countries. Analyzing co-infecting Pf revealed no resistance mutations in Pfmdr1 and Pfk13 genes, but mutations in Pfcrt (C72V73I74E75T76) and Pfdhfr-Pfdhps genes (A16C50I51R59N108L164 -...
